Abstract

The invention relates to an insecticidal water-in-oil (W/O) formulation, comprising at least one insecticidal active ingredient and at least one burning salt, and the production of said formulation. The formulation according to the invention is suitable in particular for treating suitable carrier materials, in particular paper carriers, in an economical single-step process by means of conventional application methods. The present invention further relates to insecticidal products that can smolder, which are produced by treating a carrier material with the formulation according to the invention.

Description

The invention relates to an insectiddal water-in-oil (W/O) formulation with at least one insecticîdai active substance and at least one buming sait and to the préparation of this formulation. The formulation according to the invention is particularly suitable for the treatment of suitable supports, 5 in particular of paper supports, in an economical one-step process with the aid of conventional application processes. In addition, the présent invention relates to insecticîdai, smoulderable products which can be prepared by treating a support with the formulation according to the invention.

US-A-2009/0163582 describes a water-in-oil (W/O) formulation in which a poiyglycerol fatty acid 10 ester or a sorbitan fatty acid ester is employed as emulsifïer, a pesticide, for example a pyrethroid, as active substance and acetyl ester, a methyl ester, an acetyl tributyl citrate, a white minerai oil or a combination of these as the solvent. This formulation takes the form of an aérosol formulation for the end user.

WO-A-2007/131679 describes a paper impregnated with an insecticîdai active substance. The 15 paper here is prepared in a two-step process in which the paper is first pretreated with an aqueous

6% strength potassium nitrate solution and then dried, and then, in a further step, impregnated with active substance solution. WO-A-2007/131679 does not disdose any formulation in which the paper can be treated in a one-step process, in particular with an Insectiddal active substance and the potassium nitrate sait.

WO-A-2011/092722 describes a paper Impregnated with an Insectiddal active substance, which paper, again, is prepared in a two-step process. Analogously to the process of WO-A-2007/131679, the paper is first treated with a potassium nitrate before being dried and then impregnated with the active substance.

The object of the présent invention was to provide a formulation which is chemico-physically stable 25 regarding an insecticîdai active substance (i.e. for example a pyrethroid) and a buming sait and which is therefore suitable in particular for the treatment of a support such as, for example, a paper. Preferably, the formulation is intended to make possible the treatment of the support in an economical and industrlally robust one-step process. In this one-step process, the required application welght of the formulation according to the Invention is applied to the support In one 30 process step so that the support will thereafter contain the functional formulation components such as, for example, the active substance and the buming sait in a sufficientiy and homogeneously distributed manner.

-2The formulations described In the prior art are not suitable for achieving this object. In particular, it is not possible with these known formulations to combine, in one formulation, an Insectiddal active substance together with the bumlng sait required and to employ the combination for the purpose according to the invention. In particular, such formulations lack suffident chemico-physical stability (to coalescence and creaming) and lack the rheologicai properties which are necessary for the required purpose of the invention and/or cannot be adapted simply to traditional machinery and processes for appiying the formulation to a suitable support.

Surprisingly, it has now been found that the object is achieved by a water-ln-oil (W/O) formulation comprising

a) at least one surface-active emulsifying System which has a solubility In a 16% potassium nitrate sait solution of less than 1 g/l,

b) at least one nonaqueous solvent,

c) at least one bumlng sait,

d) at least one Insectiddal active substance and

e) water.

A W/O formulation generally describes a multiphase System in which an aqueous phase Is dispersed in a continuous oil phase. The expression *oil in this context Is an umbrella term for water-lnsoluble liqulds and solvents which In mixture with water or aqueous sait solutions bring about phase séparation. Examples are aliphatic and aromatic solvents, vegetable and animal oils and their dérivatives, fragrances or mixtures of these.

in experimental terms, one differentiates between a W/O and an O/W formulation by determining the spedfic conductivity. Aqueous sait sdutions with a sait concentration of 5% by welght and higher will typically hâve a high spedfic conductivity in the mS/cm range, whiie the spedfic conductivity of aliphatic and aromatic solvents will typically be in the pS/cm range or below. As a conséquence, a buming-salt-containing formulation will experimentally be dassifted as a W/O formulation when its spedfic conductivity amounts to less than 0.1 mS/cm. The conductivity of the présent W/O formulation according to the invention is therefore preferably less than 0.1 mS/cm, measured at room température (20’C).

Surface-active emulsifiers which are suitable for the W/O formulations according to the invention as the at least one surface-active emulsifying System are those which in each case hâve a solubility in

-3a 16% potassium nitrate sait solution of less than 1 g/l (the solubility being determined by conventional processes at a température of 20°C).

Suitable surface-active emulsifying Systems which hâve a solubility In a 16% potassium nitrate sait solution of less than 1 g/l are. preferably, nonionic surface-active emulsifiers (also referred to as nonionic surface-active agents) with an HLB value In the range of from approximately 2 to approximately 10, preferably 2 to 10, more preferably between approximately 2 to approximately 8, preferably 2 to 8 and especially preferably between approximately 3 and approximately 6, preferably between 3 and 6. Some of the surface-active agents which can be used in accordance with the Invention are listed for exampie in Kirk-Othmer, Encyclopédie of Chemical Technology, 3^rt Edition, 1979, Volume 8, page 913.

The HLB value (HLB = hydrophilic-llpophilic balance) Is an empiric scale defined by W. C. Griffin (J. Soc. Cosmetic Chemists, 1, 311 (1949)) which expresses the amphiphilic nature of emulsifying agents (In particular of nonionic surface-active agents). The lowest HLB values are assigned to the surface-active agents with the lowest hydrophilicity. Processes for determining the HLB are well known in the art, and any such process can be employed for determining the HLB. A description of the HLB System and processes for determining the HLB are described In The HLB-System: a time saving guide to emulsifier sélection, ICI Americas Inc., Wiimington, Delaware, 1976.

Nonionic surface-active emulsifiers which are suitable in accordance with the Invention are especially preferably selected from the group consisting of alkylphenol ethoxylates, alkanol ethoxylates, alkylamine ethoxylates, sorbitan esters (such as the Span sériés) and their ethoxylates (such as the Tween sériés), castor oil ethoxylates, ethylene oxide/propylene oxide block copolymers, alkanol/propylene oxide/ethylene oxide copolymers, polyglycerols and polyglycerol esters.

The hydrophiliclty/lipophilicity balance (HLB) In nonionic surface-active agents may be adjusted by modifying the degree of ethoxylation.

As a further preferred embodiment of the invention, the W/O formulation preferably comprises from 0.01 to 5% by weight, more preferably from 0.01 to 1% by weight, of a colorant. Ali percentages by weight which refer to the W/O formulation of the above-described components give not more than 100% in total.

If desired, the W/O formulation according to the invention furthermore comprises additives or adjuvants, preferably antifreeze agents, bittering agents, stabiiizers, antifoam agents, wetters, antifoams and préservatives. Examples of suitable antifreeze agents are ethylene glycol, monopropylene glycol, giycerol, hexylene glycol, 1-methoxy-2-propanol, cyclohexanol, in particular monopropylene glycol. Bittering agents which are suitable are in particular aroma oiis, preferably peppermint oil, eucalyptus oil, bitter aimond oü, menthol, fruit aroma substances, preferably aroma substances of lemons, oranges, citron, grapefruit or mixtures of these, and/or denatonium benzoate. Stabiiizers which may optionally be added to the formulation are acids, preferably organic acids such as dodecylbenzenesulphonic acid, acetic acid, propionic acid or citric acid, in particular citric acid, and antioxidants such as butylhydroxytoluene (BHT), butylhydroxyanisol (BHA), in particular butylhydroxytoluene. Preferred antifoam agents and defoamers are siliconebased, espedally preferred are an aqueous émulsion of diaikylpolysifoxanes, commerciaily

-18available as Rhodorsil®; 426R from Rhodia Chimie France, Wacker SE sériés from Wacker, Germany, and a mixture of dialkylpolysiloxanes as an oil, commercially available as Rhodorsil®; 416 from Rhodia Chimie, France, Wacker 5184 or Wacker SL from Wacker, Germany.

The formulations according to the invention optionally also comprise further functional additives which effect the combustion properties or other properties of supports which are treated with the formulation according to the invention. Examples of such additives which may be mentioned are phosphate salts (such as, for example, sodium phosphates, monoammonium phosphates), organic acids (for example trisodium citrate, tripotassium citrate, sodium acetate, sodium tartrate, succinic acid, malonic acid and the like) and waxes. Further examples of such additives are minerai inorganic substances such as titanium dioxide, calcium carbonate, phyilosilicates such as kaolin, and organic fillers such as microcrystalline cellulose.

A further subject matter of the invention relates to the use of a formulation according to the invention fortreating a support.

According to the Invention treating refers to a process in which a support is brought into contact with the formulation. A suitable treatment method is imprégnation, for example by spraying the support with the formulation according to the invention, followed by drying, for example in the air, or immersing the support in the formulation according to the invention, followed by drying, for example In the air. Other suitable imprégnation processes are Imprégnation by means of a pipette. A further suitable and preferred treatment process which is particularly suitable is to print the support with the formulation according to the invention.

To print the support with the formulation, it Is preferred to employ established application processes or coating fadlities for continuous operation. Suitable printing processes and corresponding facilities are known for example from the graphies industry (direct and indirect printing processes) and from the paper industry (coating and imprégnation processes). Other known facilities/processes are the blade-coating press, the film press, the size press, the curtain coating process and others.

Espedally preferred are gravure processes, where the formulation according to the Invention is applied directly from the rotating engraved cylinder to the support.

it has emerged that the présent application is particularly suitable for being applied homogeneously to a support by means of a gravure process. Here, the formulations according to the invention remain physlcally stable and can be adapted readily to the selected gravure process In respect of the rheological properties (in particular viscosity and wetting properties). In the context of the

-19present invention, the expression physicaliy stable means that In a relevant time scale for the application of the formulation in a one-step coating process, In particuiar by means of a gravure process, no significant or macroscopie phase séparation of the water phase and the oil phase, or creaming, takes place.

Under certain circumstances, it may be necessary to adapt the viscosity of the formulation to the coating process so as to avoid undesired side-effects caused by the process (such as, for example, Inhomogeneous film splitting and misting, which may resuit in inhomogenities in the coating). In this respect, the viscosity properties are preferably controlled via altering the weight fractions of the surface-active emuisifÿing System and/or via altering the composition of the surface-active emulsifying system and/or via modîfying the proportions of the aqueous phase relative to the continuous oil phase*.

it has emerged that, when using a traditional gravure process and the preferred paper support defined hereinbelow, a Bingham viscosity of the W/O formulation according to the invention of between 20 and 200, preferably 30 to 150, mPa-s at 20°C is advantageous.

The détermination of the Bingham viscosity is based on measuring the shear stress at an •1 increasing shear rate. The resulting shear stress values [Pa] are plotted versus the shear rate (s ]. The Bingham viscosity at higher shear rates is derived as the slope of the régression line.

The viscosity Is measured at a température of 20’C using a rotary viscometer using measuring Systems of the cylinder type (also referred to as double gap Systems) standardized as specified in DIN EN ISO 321, whose shear rate can be adjusted in a defined manner, for example from Haake, Bohlin, Mettler, Contraves and others. The viscometer should make possible measurements in a •1 shear rate range of from 0.1 to 1200 s .

An advantage of the W/O formulations according to the Invention Is that the Bingham viscosity can be adjusted without employing polymeric thickeners and that, therefore, a very good and homogeneous transfer of the formulation from the engraved cylinder to the support can be ensured, even with increased production speed. Formulation residues which hâve dried on the engraved cylinder can be removed readiîy with water or with customary aqueous cleaners, in contrast to formulations with polymeric thickeners.

-20Supports which are suitable in accordance with the invention are in particular solid combustible materials such as cellulose materials, textile materials, plastic materials and the like. Cellulosebased supports are, for example, paper, board, wood, wood chippings, wood chips or sawdust, rice husks, maize cob spindles (preferably without kernels), pecan nut shells and peanut shells. Thin particle board Is also suitable as the support. A suitable cellulose-based support is described, for example, in German patent application DE 43 223 76 A1, the disclosure of which is hereby induded by référencé.

Supports made of textile materials are, for example, synthetic polyester or nylon fibres or naturel fibres such as cotton, viscose, a linen-viscose mixture or a mixture of synthetic and naturel fibres such as cellulose-polyester (synthetic paper) or cotton-polyester. Other examples are wool feltine and Trevira satin.

Supports made of polymer materials are, for example, polycarbonates, polyesters, polyamides and polyterephthalates.

Espedally preferred withln the scope of the présent Invention is the use of a cellulose-based support, in particular a paper support.

In prindple, no spedal limitations are Imposed on the paper support used hère, as long as it 1s generally suitable for taking up at least one Insectiddal active substance in question and, after Igniting and extinguishing the paper support, releasing the at least one insectiddal active substance without essentially decomposing it.

However, it has emerged that paper supports with a paper weight of preferably from 25 to 300 g/m², in particular 25 to 270 g/m², espedally preferably 25 to 250 g/m², very espedally preferably 25 to 230 g/m², further very espedally preferably 25 to 215 g/m², spedfically 25 to 200 g/m², are espedally suited to the purpose according to the invention.

Furthermore, it is preferred for the thickness of the paper support to be in a range of from 0.05 to 0.50 mm, espedally preferably 0.07 to 0.40 mm, very espedally preferably 0.08 to 0.35, furthermore very espedally preferably between 0.08 and 0.25 mm, spedfically 0.08 to 0.20 mm.

Example 2: Description of the préparation of the insectlcidal smoulderable product according to the 15 invention

To préparé the insecticidal papers, the active substance formulations described in Example 1 (Fl A, Fl B and Fl C as control), were applîed homogeneously to the entire surface of the support at a defined application weight, using a gravure process. The support employed was the offset paper Tauro Offset 90 gm (Robert Hom Group). The formulations were applied in one step using the

-25printabïlity tester PhantomQD™ Proofer (HARPER Graphies GmbH) and the screen roll 306 140 100 20.0C (theoretlcal scoop volume approximately 31 cm’/m’ and engravlng angle of 60 degrees, HARPER Graphies GmbH). The formulation was transferred directly from the engraved cylinder to a paper strip at constant pressure and an application weight of approximately 16 g/m². The printed paper strips were dried in ambient air for at least one hour and then tested for printing quality (via Visual assessment of the homogeneîty of the inking of the paper) and the smouldering behaviour.

The smouldering behaviour was checked by folding the coated paper strips iengthwise, igniting them on one side, blowing out the resulting flame and placing them onto a fireproof support so that it can smoulder away completely. The degree to which the paper strip smoulders away or carbonizes is considered to be a measure for the smouldering behaviour of the coated paper strip.
